silence all calls not blocking all robo calls
I love the "silence all calls" feature of iOS 13, but I'm finding that some callers appear to have found a way around the feature.
I delete all recent calls, voicemail, and messages daily from my phone, so I was expecting that only numbers in my contact list would be able to get past the voice mail to ring my phone. I'm still having my phone ring occassionally with numbers not in my contact list. These numbers are definitely not numbers that I have called.
Am I missing something in the settings for this feature, or have some robo callers found a way around this nifty feature?
iPhone SE, iOS 13
